Heatpump
Heatpump Hot Water Systems are energy efficient systems that will reduce your energy bills substantially if you replace your existing gas or electric hot water system. Heatpumps are a two-par system, the compressor and storage tank. The compressor draws in air and a refrigerant absorbs the heat from the air. The refrigerant is then compressed which raises the temperature and is then circulated which heats the water in the storage tank.
Heatpumps have a lower installation cost compared to evacuated tube or panel solar hot water systems as there is no need install panels or tubes on the roof and run pipes from the ground to roof. This makes for a safer installation process.
Systems vary in cost depending on the brand. Some systems are split with tank and compressor as separate units, eg Sanden Heatpumps. These can system can offer flexibility as the tank and compressor can be located separately. Other systems have the compressor located on top of the storage tank, eg Istore Heatpumps. Generally the compressors need to be mounted in a well ventilated area, usually externally.
These systems will effectively work in most climates down to -10 deg celcius and above, supplying reliable hot water throughout the year.
As an energy efficient system that contributes to reducing carbon emissions, there are government STC (Small Scale Technology Certificates) rebates available. Check out Greenbank Environmental.
Heatpumps are fast becoming a popular choice when replacing existing hot water systems.
